I have spent some time recently on updating my program(s) to handle Tops-10 backup tape images, and I am now at the stage when it seems to work "good enough", so I decided to release this as a beta test. http://www.pdc.kth.se/~bygg/tops/back10.tar The basic things work, it can create (-c), do directory (-t) and extract files (-x), and it reads tapes with large blocks, like the TSU tapes. This is very much a work-in-progress, so things might change. If you have any opinion on how things should work, please let me know. --Johnny (the PDP-10 one)
